Paraperesis: A rare complication after depressed skull fracture

Depressed skull fracture is an inward buckling of the skull bones, often because of direct blow to a small surface area of the skull with a bluntobject. Monoparesis is often among its clinical presentations, but midline depressed skull fracture presenting as motor weakness of both lowerlimbs (Paraperesis) has not yet been reported. We report the case of 55 year old male admitted to emergency department with alleged history ofhit on head by a wooden rod. He had pain, mild swelling and a small cut over scalp without any symptoms & signs of neurological deficit. On daytwo of admission patient developed weakness of both lower limbs. On CT scan patient had bilateral depressed skull fracture of high parietal boneon either side of midline. Patient was managed conservatively, made remarkable recovery and was discharged after 2 weeks.Key words: Fracture, paraperesis, edema, depressed fracture, skul

In Vitro Antioxidant and In Vivo Hepatoprotective Activity of Leave Extract of Raphanus Sativus in Rats Using CCL4 Model

Background: Raphanus sativus is reported to have a variety of biological activities. This work screened the hepato-protective and antioxidant activity of ethanol (ERS), and aqueous (ARS), extracts of leaves of Raphanus sativus in Carbon tetrachloride (CCl4), model in rats.Material and Methods: The extracts were subjected to antioxidant tests (Total reducing power and Total phenolic content), and preliminary phytochemical screening. A pilot study was done on 100 and 300 mg/kg extracts, form which 300 mg was chosen for further experiments. The albino rats (200-250 grams), were divided into 5 groups of 6 animals each (n=6). There were three control groups comprising of normal control (normal saline -1ml/kg), negative control group (CCl4 1ml/kg in olive oil in a ratio of 1:1 v/v), and positive control group (Silymarin 50mg/kg). The Test drugs were given in a dose of 300 mg/kg for both ERS and ARS extract for 7 days. Biochemical parameters (AST, ALT, Alkaline phosphatase, Total Bilirubin), histo-pathological examination of liver and in vivo antioxidant tests [CAT, GSH and MDA] were done.Results: The phytochemical study showed the presence of flavanoids, terpenoids, alkaloids, saponins and sterols. A dose dependent increase in the oxidative potential was observed in both the extracts with total phenolic content 70.1 and 44.4 GAE/g extract for ERS and ARS respectively. ERS 300mg/kg showed a significant (p<0.001) increase in levels of AST, ALT and alkaline phosphatase as compared to negative control (percentage hepatoprotection =45.3%) while ARS 300 mg/kg (p<.01) group showed 30% hepatoprotection. The GSH (p<0.001) and CAT (p<0.05) in ERS and ARS were significantly increased while MDA levels were decreased (P< 0.01), as compared negative control. The findings were confirmed histo-pathological examination.Conclusion: The ethanol and aqueous extract of Raphanus sativus have partial hepatoprotection against CCl4 toxicity.Key words: Raphanus sativus, hepatoprotection, CCl4, antioxidant

Comparison of the elastic recovery and strain-in-compression of commercial and novel vinyl polysiloxane impression materials incorporating a novel crosslinking agent and a surfactant

This study aims to formulate experimental vinylpolysiloxane (VPS) impression materials and compare their elastic recovery and strain-in-compressions with three commercial VPS materials (Aquasil, Elite, and Extrude). Five experimental materials (Exp), two hydrophobic (Exp-I and II) and three hydrophilic (Exp-III, IV and V) were developed. Exp 1 contained vinyl-terminated poly-dimethyl siloxane and a conventional cross-linking agent (poly methylhydrosiloxane), while Exp- II contained a novel cross-linking agent that is tetra-functional dimethyl-silyl-ortho-silicate (TFDMSOS). Exp III–V (hydrophilic materials) were formulated by incorporating different concentrations of non-ionic surfactant (Rhodasurf CET-2) into Exp II formulation. Measurement of elastic recovery and strain-in-compression for commercial and experimental materials were performed according to ISO4823 standard using the calibrated mechanical testing machine (Tinius Olsen). One-way analysis of variance (one-way ANOVA) and Tukey’s post-hoc (HSD) test were used for statistical analysis and a p-value of ≤ 0.05 was considered significant. Exp-I has statistically similar values to commercial VPS. The Exp-II showed the highest elastic recovery, while % elastic recovery was reduced with the addition of the non-ionic surfactant (Rhodasurf CET-2). The % reduction was directly related to the concentration of Rhodasurf CET-2. In addition, Exp II had significantly higher strain-in-compression values compared to Exp-I and commercial materials. These values were further increased with the addition of a non-ionic surfactant (Rhodasurf CET-2) was added (Exp-III, IV and V)

Synthesis of 3-[4-(2-furoyl)-1-piperazinyl]-N- (substituted)propanamides as promising antibacterial agents with mild cytotoxicity

Purpose: To evaluate the antibacterial activity and cytotoxicity of a series of molecules with amalgamation of furoyl, piperazine and amide moieties.Methods: New derivatives, namely 3-[4-(2-furoyl)-1-piperazinyl]-N-(substituted) propanamides, were synthesized and evaluated for their antibacterial activity and toxicity to mammalian cells. The synthesis was initiated by treating different aryl/aralkyl amines (1a-u) with 3-bromopropionyl chloride (2) to obtain the solid electrophiles 3a-u, which were collected by filtration. Thereafter, the different N-aryl/aralkyl-3- bromopropionamides (3a-u) and 2-furoyl-1-piperazine (4) at equimolar ratios were allowed to react in acetonitrile and in the presence of a base, K2CO3, to form the target compounds, 5a-u. Structural elucidation was carried out using EI-MS (electron impact mass spectrometry), IR (infrared) and 1H-NMR (proton nuclear magnetic resonance). The antibacterial activity of the synthesized compounds was evaluated against various bacterial strains. Furthermore, hemolysis was determined to assess cytotoxicity using bovine red blood cells.Results: Molecules 5g, 5a, 5p, 5g and 5i were found to be potent agents against S. aureus, S. typhi, P. aeruginosa, E. coli and B. subtilis with respective minimum inhibitory concentration (MIC) values of 8.34 ± 0.55, 8.37 ± 0.12, 8.65 ± 0.57, 8.97 ± 0.12 and 9.24 ± 0.50 μM, compared to 7.80 ± 0.19, 7.45 ± 0.58, 7.14 ± 0.58, 7.16 ± 0.58 and 7.29 ± 0.90 μM for the reference standard, ciprofloxacin. The most active compounds, 5a, 5g, 5i and 5p, showed a hemolysis of 15.48, 8.03, 5.52 and 4.35 %, respectively.Conclusion: The synthesized compounds exhibit good antibacterial activity. The hemolysis data indicate that these compounds have a low toxicity level. However, in vivo studies are required to ascertain their potentials as new drug candidates.Keywords: 4-(2-Furoyl)-1-piperazine, 1H-NMR, EI-MS, Antimicrobial activity, Hemolytic activit

Payment methods and patient satisfaction among type-2 diabetes patient at a teaching hospital in Malaysia

Diabetes mellitus is a costly chronic disease related to medication, physician consultation and laboratory investigation. The main means of financing healthcare include direct out-of-pocket (OOP) payment and government subsidisation in some countries, or public/private health insurance schemes, or a mix of all. Patient satisfaction is critical in ensuring the use of healthcare services, continuity of care and treatment adherence. In this study, we determined the satisfaction of type 2 diabetes mellitus (T2DM) patients regarding the healthcare services and payment methods at Universiti Kebangsaan Malaysia (UKM) Teaching Hospital, Malaysia. This cross-sectional study involved 313 T2DM patients aged ≥18 years who were included after clinical consultations. We used convenience sampling at the outpatient and inpatient medical centres of Hospital Canselor Tuanku Muhriz and UKM Specialist Centre. A survey consisting of sociodemographic, socioeconomic and payment method types as well as a validated patient satisfaction questionnaire scale were used. The mean age was 59.6 years (SD=13.151), 53.0% of the patients were female, 78.3% were Malay, 76.4% were uninsured, 39.6% were covered by government subsidies, while 36.7% paid OOP. Around 86% were generally satisfied with the overall services. Patients were most satisfied with technical quality (84%), communication skills (83%) and accessibility (80%), but satisfaction was lower in doctors’ service orientation, particularly the interpersonal manner (73%), financial aspect (73%) and time spent with the doctor (70%). Over 86% of patients were satisfied with healthcare services and payment methods; however, patients who paid OOP reported low satisfaction. Full insurance and extending benefits to partially cover both inpatients and outpatients with low co-payment is recommended to increase satisfaction

A New Method for Morphometric Analysis of Tissue Distribution of Mobile Cells in Relation to Immobile Tissue Structures

The distribution of cells in stained tissue sections provides information that may be analyzed by means of morphometric computation. We developed an algorithm for automated analysis for the purpose of answering questions pertaining to the relative densities of wandering cells in the vicinity of comparatively immobile tissue structures such as vessels or tumors. As an example, we present the analysis of distribution of CD56-positive cells and of CXCR3-positive cells (relative densities of peri-vascular versus non-vascular cell populations) in relation to the endothelium of capillaries and venules of human parietal decidua tissue of first trimester pregnancy. In addition, the distibution of CD56-positive cells (mostly uterine NK cells) in relation to spiral arteries is analyzed. The image analysis is based on microphotographs of two-color immunohistological stainings. Discrete distances (10–50 µm) from the fixed structures were chosen for the purpose of definining the extent of neighborhood areas. For the sake of better comparison of cell distributions at different overall cell densities a model of random distribution of “cells” in relation to neighborhood areas and rest decidua of a specific sample was built. In the chosen instances, we found increased perivascular density of CD56-positive cells and of CXCR3-positive cells. In contrast, no accumulation of CD56-positive cells was found in the neighborhood of spiral arteries

A review of information flow diagrammatic models for product-service systems

A product-service system (PSS) is a combination of products and services to create value for both customers and manufacturers. Modelling a PSS based on function orientation offers a useful way to distinguish system inputs and outputs with regards to how data are consumed and information is used, i.e. information flow. This article presents a review of diagrammatic information flow tools, which are designed to describe a system through its functions. The origin, concept and applications of these tools are investigated, followed by an analysis of information flow modelling with regards to key PSS properties. A case study of selection laser melting technology implemented as PSS will then be used to show the application of information flow modelling for PSS design. A discussion based on the usefulness of the tools in modelling the key elements of PSS and possible future research directions are also presented
